[MFC]选择目录对话框和选择文件对话框

在MFC编程中经常会需要用到选择目录和选择文件的界面，以下总结一下本人常用的这两种对话框的生成方法：

选择目录对话框

// 选择目录按钮
void  CDcPackerDlg::OnBnClickedDecgen()    
{
    char szPath[MAX_PATH];     //存放选择的目录路径 
    CString str;

    ZeroMemory(szPath, sizeof(szPath));   

    BROWSEINFO bi;   
    bi.hwndOwner = m_hWnd;   
    bi.pidlRoot = NULL;   
    bi.pszDisplayName = szPath;   
    bi.lpszTitle = "请选择需要打包的目录：";   
    bi.ulFlags = 0;   
    bi.lpfn = NULL;   
    bi.lParam = 0;   
    bi.iImage = 0;   
    //弹出选择目录对话框
    LPITEMIDLIST lp = SHBrowseForFolder(&bi);   

    if(lp && SHGetPathFromIDList(lp, szPath))   
    {
        str.Format("选择的目录为 %s",  szPath);
        AfxMessageBox(str); 

        
    }
    else   
        AfxMessageBox("无效的目录，请重新选择");   
}

选择文件对话框

CString CDcPackerDlg::BootOpenDialog()    // 返回选择的文件名称
{
    CString strFile = _T("");

    CFileDialog    dlgFile(TRUE, NULL, NULL, OFN_HIDEREADONLY, _T("Describe Files (*.cfg)|*.cfg|All Files (*.*)|*.*||"), NULL);

    if (dlgFile.DoModal())
    {
        strFile = dlgFile.GetPathName();
    }

    return strFile;
}

// 加载文件按钮
void  CDcPackerDlg::OnBnClickedSelectdec()
{
    // TODO: Add your control notification handler code here
    m_strDescPath = "";        //类的成员变量

    //"打开文件"对话框，选择文件，返回其路径
    m_strDescPath = BootOpenDialog();

    
}
